Construction of daily precipitation series and the observational characteristics of extreme precipitation in Tianjin,China during 1888-2022

Given the difficulties in rescuing and ensuring the quality of long-term climate data,current studies on century-scale climate change are usually limited to annual and monthly data,resulting in the poor detection of extreme climate events and their changes before 1950.In this study,we reconstructed a daily precipitation series for Tianjin from 15 September 1887 to 31 December 2022 on the basis of the most comprehensive daily precipitation records collected from the Tianjin Meteorological Archive,China,and in reference to the precipitation analysis results based on the datasets developed by the Climatic Research Unit Time-Series version 4.06,Global Precipitation Climatology Centre and University of Delaware along with the application of various homogenisation methods for climate series.Our approach provides a complete and reliable century-long daily precipitation series for the study of regional or local extreme weather and climate events.The reconstructed daily dataset reveals that the annual precipitation amount and R95 intensity in Tianjin during 1888-2022 lack significant trends and have values of 0.74±6.99 and-1.84±3.22 mm per decade,respectively.On the annual and seasonal scales,the precipitation amount and R95 intensity,particularly those in autumn,have increased since the latter half of the 20th century relative to those in 1888-1950.However,the increase in precipitation amount and R95 intensity is relatively limited compared with that in atmospheric water vapour content due to surface warming,indicating the highly sensitive response of extreme precipitation events to warming.In addition,the estimates for the return periods of 5,10,20,50 and 100 years covering 1888-2022,1888-1950 and 1951-2022 depict that the intensity of heavy rain and above magnitude was highest in 1888-1950 and decreased in 1951-2022.

Creating a New Form of Rule of Law Civilization:A Historical Narrative of the Communist Party of China

The modernization path of the Chinese rule of law reflects the glorious process of the Communist Party of China(CPC)’s continuous exploration of the rule of law development.It has created a new form of rule of law civilization for humanity,one that has not only profoundly changed China but is also deeply influencing the world historical process.Under the leadership of the CPC,the Chinese people have achieved the innovation of legal mechanisms,text,and discourse in their century-long endeavor for the rule of law.This highlights the distinctive features of the Chinese rule of law civilization.The innovation of legal mechanisms is the foundation of the modernization of the Chinese rule of law,indicating that through the Party’s century-long endeavor for the rule of law,a legal leadership mechanism has been formed,in which the Party exercises overall leadership and coordinates the efforts of all sides;the innovation of legal text is the manifestation of modernization of the Chinese rule of law,indicating that through the Party’s century-long endeavor for the rule of law,the socialist legal system with Chinese characteristics is gradually moving toward a new stage of codification in which the promulgation and implementation of the Civil Code of the People’s Republic of China is a milestone;and the innovation of legal discourse is the core of modernization of the Chinese rule of law,indicating that through the Party’s century-long endeavor for the rule of law,the continuous refinement of the Chinese legal discourse system is playing a key role in providing theoretical support and legal reasoning.
